Title: Automatic measuring casting method
Inventor: TAKATSU YOSHIHIRO
IPC: G01G17/04
Filed: 1983-12-12
Abstract: PURPOSE:To form a smooth outside surface by setting the speed of a pan to a value slightly lower than the going speed of a mold on a moving table and charging a molten metal from a molten metal charging hole of the pan into the plain mold while changing the dropping point of this molten metal successively. CONSTITUTION:A prescribed quantity of the molten metal is put in a pan 3, and a turntable 17 is rotated in this state, and a plain mold 4 placed on the table 17 is set to a prescribed position, and a truck driving device 15 is driven while continuing the rotation to move a truck 5 in the mold going direction of an arrow (a) in the same speed as the mold, and the pan 3 supported by a movable frame 6 is lifted through leading-in operation of a cylinder 13, operation of a link arm 11, etc. The molten metal is charged while directing a molten metal charging hole 3' downward by a difference of length between the link arm 11 and an arm 10, and the going speed of the pan 3 is made lower than that of the mold 4. When the pan approaches the casting completion point, the pan including cylinder 13 is restored slightly to reduce the quantity of the molten metal discharged from the molten metal charging hole 3', and the cylinder 13 and the driving device 15 are restored to return the pan to the original position.

Title: Phase modulation wave direct reproduction circuit
Inventor: KATO HARUHIKO
IPC: H04L27/18
Filed: 1990-09-03
Abstract: PURPOSE:To attain phase identification and reproduction by utilizing it that a, phase of an output of a feedback type frequency divider circuit has the number of stable points corresponding to frequency division number and using an external signal so as to lock the circuit forcibly to any phase in the stable points. CONSTITUTION:A frequency (NF) being a multiple of just N-times carrier frequency of an N-phase modulation wave is inputted to a signal terminal of a frequency conversion circuit 10, an output of the circuit 10 is multiplied by a multiple of (N-1) and the result is fed back to a local oscillation terminal 12 of the circuit 10. Then the amplitude of the loop gain and the phase condition are set to that the loop acts like positive feedback loop, then a 1/N positive feedback type frequency divider circuit is formed and the output phase has N-sets of stable points. Thus, when a signal is injected forcibly to the loop circuit externally, locking to the stable point closest to the phase of the external signal is caused and even when noise or distortion exists in the input signal, the signal is obtained at the output of the frequency converter while the noise or the like is eliminated. Thus, the reproduction relay is implemented without modification of the carrier and demodulation of the phase modulation wave.

Title: Device and method for etching
Inventor: OMI KENJI
IPC: C23F1/08
Filed: 1988-09-19
Abstract: PURPOSE:To etch Al and an Al alloy into desired forms with high accuracy by making up a structure so that dry etching is performed by adding an N2 gas into a reaction tube in addition to providing reaction gases of Cl2 and CHCl3. CONSTITUTION:An etching gas is supplied in a reaction tube 10 and etching is performed by generating plasma in electrodes 11 and 12. In such a case, a mixed gas which is obtained by adding an N2 gas to Cl2 and CHCl3 gases is used as the etching gas. In other words, the Cl2 gas is supplied from a supply port 15 into the reaction tube 10 and a mixed gas of the N2 gas and an HCl3 gas is supplied from a supply port 16. When plasma is formed between the electrodes 11 and 12 by the high frequency output of a power source 13, the etching gas is converted into an active radical in plasma and then, an Al layer is etched when a reaction takes place between the Al layer on a wafer 20 and the active radical. As the etching gas contains the N2 gas, the N2 gas functions as a protective substance for sidewalls of an Al pattern and thus side etching decreases exceedingly on the Al layer. This approach facilitates etching control.
